COMBINATION LOCK-NUT WASHER AND 130m.

Application filed March 2, 1911. Serial No. 611,842.

. curely from moving in either direction, wi hlocking washer and the part through which the bolt passes.

out any direct engagement between the nut Another object of the invention is to pro vide a device whereby the washer may be maintained relative to the nut independently ofthe object to be clamped.

With these-and other objects in- -view as] will more fully appear as the description proceeds, the invention consists in"certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim,

' For a full understanding of the. invention,

reference is to behad to the following de-- scription and accompanying drawings, in

. which:

Figure 1 is a perspective view of my invention; Figs. 2 and 3 are elevations thereof, Fig. 3 being partly in section; Figs. 4 and 5 are transverse sectional views; Fig. 6 is a detail'perspective view of a modification of f at the nut locking washer.

Correspondingand like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referringto the drawing, the numeral 1 design'ates'a bolt which is provided at one end with any form of head 2 and which may also beprovided, if desired, with the ordinary fins 3, wherebythe bolt may be prevented from turning in the fish plate or other part to which it is secured;

& designates the threaded portion of the boit, the same being formed with a longitudinal groove 5 interrupting the threads, said groove being provided "with any desired number of'transversely elongated bottom deinF1g. 3.

ofany desired thickness andsize according to the work required of it, said washer being preferably circular, as shown, andprovided with a nib 8 projecting into the bolt -receiving opening of the Washer. The

washer 7 is 1, iso formed with a tongue 9 which is preferably located contiguous to the nib or lug 8, the washer being cut away, to form the tongue 9, and the latter being rectangular with parallel side edges, whereby it may be easily turned over the side of the nut (j and lie fiat'against such side, as clearly illustrated in the drawing. In the practical use of this form of washer, the washer is slipped over the threaded end of the bolt, the lug 8 sliding in the groove 5, and the nut 6 is then screwed on to the required extent,

whereupon the locking tongue 9 is bent down overone side of the nut. It is to be particularly noted that in hammering upon the tongue 9 over the nut, when the nut and washer are properly adjusted for this operation, the lug 8 will engage in one of the bottom depressions 5 .0f.th e groove 5; hence, as willbe readily understood, the washer 7 may be held from moving in either direction, ti 1 being a desideratum, whenever it'is necessary that the washer shall not bind against or contact with the part in which the bolt is mounted as for instance when employed where considerable movement or play is desired between the nut and the object through which the bolt passes. Another object of this arrangement is that the. distance to which the nut is to be turned may be accurately gaged and'the washer forced to a pre determined position and the nut then turned until it engages the washer and the washer then looked to the bolt. The improved vice is thus capable ofbeing employed to advantage in many localities where the ordinary bolt and nut cannot be used without danger of-the nut becoming loosened. This is an important feature of applicants device and materially increases its eflicieney and utility.

It isto be clearly understood that my iii-- vention is not limited to any particular location for the groove in the bolt or the lug and.

tongue of the washer, .thatany number of grooves, lugs and tongues may be employed, andthatthe lugs and. grooves may be of any desired shape in sovfar as such changes fall 'within the scope of the claim. :If desired,

the-tongue may be split. as shown at 9 in Fig. '6, wherebyonly a.port-ion of the tongue x may he initially used so that if such portion should break the remaining portion may be used in the emergency.

Having thus described the invention, What is claimed as new is:

In a look nut, a bolt having a groove extending longitudinally of he threacled end and wit-11' a plurality of depressions in the bottom of the groove, a not engaging the bolt, a Washer engaging around the bolt and having a fin directed inwardly and mlapted to engage in the groove and inio the depressions and with an outwardly directed wing to bend over the nut after the same has been locked at a predetermined point on the bolt, said fin being adapted to yield and successively enter the depressions as the nut is rotated and to remain in the nearest depression when the nut is located at the required, point upon the bolt.

In testimony whereof I affix my signature in presence of two witnesses.
